Hey guys I know this is basic stuff but for the C3 JAN 08 paper Q)7)c)
I get up to (2x+0.927...)= - 2pi, - pi, 0, pi, 2pi.
But I messed up trying to find the values of x.
I divided all the answers by 2, then did minus 0.927...
I know you could have just put it all in the calculator at the same time but can anyone tell me why this is wrong?
